  <p>Replacement nuts for fastening components on slicers, meat grinders, graters and other professional machinery.</p> <p><strong>Materials</strong>: <strong>stainless steel</strong> (resistant to corrosion and frequent washing), <strong>chrome-plated steel</strong> and <strong>brass</strong> — the right choice depends on the operating environment and the material of the rest of the fasteners.</p> <p><strong>Available threads</strong>: metric from M3 to M24 and imperial (e.g. 1/4", 3/8"), plus special versions such as <strong>self-locking</strong> nuts (with an insert that prevents loosening from vibration) and <strong>blind</strong> nuts (closed on one side, for a visually clean finish).</p> <p>For screws and other fasteners, go back to <a href="/en/viteria.html">Fasteners</a>.</p> <p><strong>Frequently asked questions</strong></p> <p><strong>When is a self-locking nut worth using?</strong><br>On components subject to continuous vibration (e.g. moving parts of machinery), where a standard nut risks loosening over time.</p> <p><strong>Metric or imperial: how do I tell them apart?</strong><br>Metric nuts are marked with "M" followed by the diameter in mm (e.g. M10); imperial ones use a fractional measurement (e.g. 1/4", 3/8") — they are not interchangeable.</p>

  COUNTERSUNK SCREWS

  <p>Countersunk screws have a conical head that sits flush with the surface, for a clean-looking fixing on machinery and visible components.</p><p><strong>How to choose the right part</strong>: you need the <strong>thread diameter</strong> (from 3 to 8mm) and the <strong>length</strong> (from 8 to 50mm) — both figures must match the original screw, or the seat/hole it fits into.</p><p><strong>Material</strong>: stainless steel, resistant to corrosion and frequent washing, suitable for food environments.</p><p><strong>Head type</strong>: slotted (flat screwdriver), for simple fixing with common tools.</p><p>For other fasteners go back to <a href="/en/viteria.html">Hardware</a> or <a href="/en/nuts.html">Nuts</a>.</p><p><strong>Frequently asked questions</strong></p><p><strong>How do I measure the countersunk screw I need to replace?</strong><br>Measure the thread diameter and overall length with a caliper: both figures are needed for the correct part.</p><p><strong>Why a countersunk head instead of a normal head?</strong><br>It sits flush with the surface, avoiding protrusions that could interfere with other moving parts or be hazardous to the touch.</p>
